Filed: 1943-11-04
Abstract: 566,916. Making compound forms. MOND NICKEL CO., Ltd. Nov. 4, 1943, No. 18325. Convention date, Nov. 26, 1942. [Classes 83 (ii) and 83 (iv)] [Also in Group II] Soldering.-In making composite articles, such as plates, sheets, slabs, rods, tubes, consisting of a layer of a chromium alloy and a foundation metal, a protective metal powder incorporated in a substantially moisture-free vehicle is applied as a coating to the alloy surface to prevent oxidation thereof and the coated surface and the clean surface of the foundation metal are brought into contact and the assembly subjected to heat and pressure to bond them together. The chromium alloy layer may consist of a nickel-chromium or a nickel-chromium-iron alloy, such as 80 per cent nickel, 14 per cent chromium and 6 per cent iron, or stainless chromium or nickel-chromium steel, the foundation metal may consist of plain carbon or low alloy steel or copper or copper alloy. The powdered metal may consist of nickel, aluminium, cobalt, copper, iron, silver or alloys or mixtures thereof and in the form of flakes or produced by the decomposition of a carbonyl or by electric deposition, grinding or like processes. Nickel flakes are preferably used with a chromium alloy containing iron or nickel or both and a foundation metal of steel. The moisture-free vehicle may consist of kerosene, but other aliphatic hydrocarbons including low melting point paraffins, aromatic hydrocarbons, such as toluol, may be used in place of or in combination with kerosene. Volatile aldehydes and ketones and other organic materials including lacquers decomposing into products such as hydrogen, hydrocarbons and carbon monoxide, but not water vapour may also be used. The surface of the alloy is first cleaned, e.g. by grinding or pickling and the powder then applied as a paint by brushing, spraying or dipping. One or more coats may be applied, the thickness of the coating amounting to at least 0.015'. The vehicle may be allowed to evaporate in part before the coated surface is applied to the foundation metal. The surface of the latter may also be similarly coated with the same or a different metal powder if the protective metal does not bond readily to the foundation metal. When the parts have been brought into contact, the edges are fusion welded together, leaving a number of unwelded outlets for the escape of the residue of the vehicle and the parts are heated to from 2000 to 2300‹ F. preferably in a furnace containing a neutral or reducing atmosphere or by enclosing the assembly in a sheet metal container air-tight except for small vent holes. Pressure may be applied hydraulically in the furnace or by forging or rolling outside the furnace. A chromium alloy layer may thus be applied to each side of the foundation metal. A number of units may be stacked together so that they may be made at the same time, the units being separated by a parting material such as alumina or magnesia. Specification 436,329 is referred to.
